7 ECONOMIC ANALYSIS 7.1 Review of the Economic State of the B.C. Fish Processing Industry This section provides a general overview of the economic state of the B.C. fish processing industry based mainly on information obtained from the Ministry of Agriculture, Fisheries and Food (MAFF). A detailed economic analysis of the status of the industry can not be presented, as this would require a review of the profits and losses of individual processing companies. Such information is not readily available and companies are reluctant to provide this kind of data. The analysis below is, therefore, restricted to information about the wholesale and landed value of B.C. seafood. Figure 7.1 shows the historic landed and wholesale value of all B.C. seafood for the years 1978 to 1992 (MAFF, 1992). The wholesale value experienced a sizable increase in the period from 1984 to 1990, after which time the industry experienced a downturn which, according to the 1992 data (latest year for which data is available) seems to have Ievelled off. The changes in the wholesale value generally follow those in the landed value, although fluctuation of the latter are not as pronounced as the changes of the former. The wholesale values generally were 170 % to 200$40 of the landed value of seafood, and reached $879 million in 1992, down from a high of $1033 million in 1990. A breakdown of wholesale values according to contribution by species is presented in Table 7.1 for the years 1990-1992. In this time period, salmon products accounted for 57 to 63 % of all seafood, with the contribution of farm salmon increasing steadily from 8.2 to 16.5 % This increase in the contribution of farm salmon to the total wholesale value of B.C. seafood is due to the drop in landings of wild salmon and an increase in the farm salmon production. Herring and groundfish contributed approximately equally to the total wholesale value (average for the years 1990 -1992:15.9 % and 13.3%, respectively). The remainder was ‘ made up by shellfish, halibut, farmed trout and other fish. Table 7.2 shows the average per-tonne wholesale and landed value, and their ratios for each species for the years 1990 to 1992. in general, the highest wholesale and landed vaIues/tonne were obtained for halibut and farmed trout, followed by salmon (both wild and farmed), herring and shellfish. The lowest values were obtained for groundfish (approximately $800 per tonne). However, comparing the ratios of the per-tonne 87
